In Mr. Good, Peng Jiahe caught a cold and had a fever. Lu Yuan gave her a glass of Brandy. This scene appeared in the third part of the novel, which was after Peng Jiahe had recovered and was together with Lu Yuan. Brandy was a mixture of alcohol and spices, usually used to make cocktails or as a substitute for white wine. Although Brandy can have a certain feverish effect, excessive consumption will still cause harm to the body. Therefore, it was not recommended for ordinary people to drink large amounts of Brandy to reduce their fever. As for the novel's mention of igniting a fire and boiling water to reduce fever, it was a fictional method that did not apply to all types of fevers. Usually, for mild fevers, traditional methods such as wiping the forehead and soaking the feet in warm water could be used to relieve the symptoms. If the fever is serious, it is recommended to seek medical advice or seek the help of a professional doctor.
